Tuberculosis in Pacific salmon and steelhead trout

Creator:: Wood, James W., Ordal, Erling Josef, 1906-, and Oregon. Fish Commission
Abstract:: Tuberculosis in salmonoid fishes was first observed in the 1952 run of fall chinook salmon (Oncorhynchus tshawytscha) returning to the Bonneville Hatchery of the Oregon Fish Commission. In the studies reported here, tuberculosis was found not only in adult spring chinook but in silver salmon (0. kisutch), blueback salmon (0....

A winter steelhead tagging program on the Columbia River

Creator:: Korn, Lawrence and Oregon. Fish Commission
Abstract:: The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...

Oregon coastal salmon and steelhead tagging programs

Creator:: Henry, Kenneth A. and Morgan, Alfred R.
Abstract:: Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...

Cormorant harassment to protect juvenile salmonids in Tillamook County, Oregon

Creator:: Bayer, Range D., 1947-
Abstract:: The goal of the Oregon Plan is to restore wild coho and wild steelhead runs. Under the federal Endangered Species Act, wild coho salmon along the Oregon Coast are listed as Threatened and wild Oregon Coast steelhead are a candidate for listing.

Seasonal life history of Oncorhynchus mykiss in the South Fork John Day River Basin, Oregon

Creator:: Tattam, Ian A.
Abstract:: Understanding seasonal changes in growth, survival, and movement rates is crucial to salmonid management. These life history characteristics provide a context for evaluation of management actions. We evaluated the life history of individually marked Oncorhynchus mykiss gairdneri in the South Fork John Day River basin in Northeastern Oregon. This thesis...

Effects of estuarine circulation patterns and stress on the migratory behavior of juvenile salmonids (Oncorhynchus sp.)

Creator:: Truelove, Nathan Kobun
Abstract:: For the first objective of this thesis, we attempt to understand the role of water flow and directionality in determining steelhead (Oncorhynchus mykiss) and spring/summer and fall Chinook (O. tschawytscha) migration patterns within the Columbia River Estuary and plume by integrating recent advances in biotelemetry and environmental observation and forecasting...
